Karatium white

ABSTRACT

A jewelry alloy that is approximately a 10% or 2.4 karat alloy that has similar color huge and shine and characteristics of 10 karat white gold and higher. This alloy is considerably less expensive than traditional 10 karat white gold and higher, but has all the similar working characteristics as working in sterling or 10 karat white gold metal alloys. The alloy has the following compositions by weight; Gold 5.00-20.00%, Silver 75.00-92.50%, Copper 01.00-10.00%. In addition to its nice white (silver) color and low cost it provides retailers with an affordable alloy for jewelry and provides jewelry craftsmen a low cost white (silver) alloy that responds well to the jewelry manufacturing process (e.g., casting, milling, soldering, tooling, stone setting, polishing and plating).

Background of Invention

Even before the recent increase in the price of precious metals in thisestranged economy I found an artistic purpose to develop new coloredalloys that would be wearable and easy to work in. Then in 2006 I begandeveloping a (pink) silver colored metal while blending differentpercentages of elements I came up with this white color alloy. Aftermany tests I found that with this small percentage of pure gold, itgives Karatium White a little nicer polish and luster than traditionalsilver.

Continuing tests of this new alloy proved very positive to casting,fabricating and polishing as used in the jewelry industry. As designerof this new alloy I felt it mandatory that any new well priced alloyhave the same characteristics as traditional sterling silver and 14karat white gold, this to enable any craftsmen to start working in thisalloy immediately. After the final development of this new alloy I madecontact with the Jewelers Vigilance Committee and learned that becausethis metal is less than 10 karat and has less than 900 fine silver Icould not use the word gold or silver in correspondence to any name forthis alloy. Hence the name Karatium White that is a made up name that Ihave trademarked. Karatium actually comes in 2 additional colors Yellowand Pink, and a Sterling version which I have also submitted for PatentApplication

1. A white metal alloy of 2.4 Karat that has a good white (silver) color and resist tarnishing and the discoloration of skin.
 2. Has all of the same jewelry workability as sterling and 10 karat white gold or higher.
